Hmm, this is a well-done story. I like aspects of it.
Well, looking at others works by Melissa N., it's as I suspected, this is the only one that has the 'femdom' tag and it's likely just because she exists as a plot device to guide the MC in their MtF gender transformation, and probably the MC will fuck men after she's done with them, so it's not up my alley as someone who found it by searching for the 'femdom' tag. Still, it's impressive...
